We have social media overload and the majority of it is fragmented.
Facebook wins by numbers, but as you quite rightly say no reward, if anything we are willing slaves to provide content.

Another started recently in my area called NextDoor! Yawn! enough!
RIP a whole bunch others, so the desire is there to find the ultimate platform that can do it all and provide an income.
So, Steemit wins. It gives reward and it's indexed by Google. Which is one of the things I have been testing while creating content on Steemit.
So, can this platform deliver where others have failed, I really think so. Can it be used for a community why not, can it create 100,00 jobs you could classify it by, if you earning from Steemit it is a job already!
